Length 81m Design Load HS20-44 Steel Girder Bridges

                                         
Description of Length 81m Design Load HS20-44 Steel Girder Bridges :        

Length 81m Design Load HS20-44 Steel Girder Bridges are deck bridges which are used for short and medium spans, for highway bridges composite deck construction is generally used unless the depth is very critical in which case half-through girders or through trusses may be necessary.
                           

Length 81m Design Load HS20-44 Steel Girder Bridges surface protection can be paint or hot-dip galvanized.

Length 81m Design Load HS20-44 Steel Girder Bridges load capacity, width can be designed according to user's requirements

Introduction of Length 81m Design Load HS20-44 Steel Girder Bridges :                                                  

Length 81m Design Load HS20-44 Steel Girder Bridges is a standard bridge equipment, adopted extensively and the most popular in the world


Advantage of Length 81m Design Load HS20-44 Steel Girder Bridges :
 

Possessing the features of humble structure,
suitable transport, rapid erection
easy-going disassembling,
weighty loading capacity,
huge stability and lengthy fatigue life
being capable of an alternative span, loading capacity

      
Features of Length 81m Design Load HS20-44 Steel Girder Bridges:
 

1. Great strength and enormous stiffness , relative to the concrete bridge can be reduced trabecular high and self-confidence
2. Due to the steel isotropic, quality of a material is uniform and modulus of elasticity, that make steel bridge in the working condition and calculation compared with the assumption
3. Steel bridge usually USES factory, site splicing, the construction period is small, processing convenient and not affected by seasonal effect.
4. Steel bridge is fit for industrialized manufacture and very suitable to transport.
5. Steel bridge is informal to repair and replace, long generation, material can be recycled.

Application of Length 81m Design Load HS20-44 Steel Girder Bridges:

Beam bridge,arch bridge,rigid frame bridge,cable-stayed bridge,suspension bridge. passenger foot-bridge


Mixture form to erect all kinds of Length 81m Design Load HS20-44 Steel Girder Bridges:
 

Impermanent Bridges, Spare Bridges and Secure Bridges.
Using the bridge equipment, the interruption bridges of mixed span can be erected.
The bridge has the advantages of few components, light weight and little cost.
Bailey Bridge requires no unusual tools or heavy equipment for construction, the bridge elementsare small enough to be carried in , and the bridge is strong enough to carry . It is considered a huge example of military engineering.


The compact 200 panel bridge: The compact 200 panel bridge is alike to the compact 100 panelbridge from their appearance. The variance is its increased panel height to 2.134m. It employed the method of alternating joints between Reinforcement Chords and the joints between panels. This method can decrease inelastic deformation caused by the oversized pinholes.
Pre-arch method is used to moreover cut down mid-span and vertical deflection to a larger degree.
Bolt-connected components use the orienting sleeve- fixing method to increase accuracy of connections. Shear is created in orienting sleeves and tension is developed in bolts, which increase the usage life of the bolts and ensure the safety of panel bridges. Wind resistant brace is made to be composite type and is connected to transom/girders to improve overall stability of panel bridges.

Competitive Advantage of Length 81m Design Load HS20-44 Steel Girder Bridges:


Heavy loading capacity     
Used as permanent bridge
Good stability
Simple in structure
Long service life
Rapid in erection
No headroom limit
No width limit
